According to Samantha Markle, Engelson, a Hollywood producer, is fed up with how he’s been treated during the duchess’ whirlwind romance to Prince Harry.

“He said he was devastated, that he felt like a piece of gum at the bottom of his shoe,” Samantha told the Sun. “He slammed Meg.”

The 53-year-old author claims Trevor was laying low around the time of the royal wedding and the media circus that surrounded it over fears of a Hollywood backlash, but has had enough.

Engelson was, at a time, reportedly even planning a comedy loosely based on Meghan, with the plot focusing on an American man forced and his ex, who just so happens to marry into the British royal family. The series, allegedly in the works at Fox, would have focused on the former couple attempting to navigate custody.

While there were reports back in May that the project was killed, Samantha claims Trevor won’t “back down” when it comes to getting his show across the line. “It’s not directly about her and she doesn’t have a copyright on all things royal,” she told the Sun.

Engelson, who is 5 years older than Meghan, met the Suits actress in 2004 and they were together for 7 years.

It was when Meghan relocated to Toronto in Canada from Chicago, Ill., for her role as s Rachel Zane on the hit legal drama that the relationship reportedly started to disintegrate. The distance — Engelson stayed behind in the states — apparently took its toll and the pair called it quits, with Meghan reportedly sending her wedding and engagement rings back in the mail.
